I have ran Duallys since '94. My wifey puts on as many or more miles on it than I doo. And she likely hauls more weight/miles than I doo. (business)
We put on a flatbed about 8-9 yrs ago now. MAN I love that thing! It's great for loading skids on - and keeping the weight up to the headache rack where it is more stable as well as doesn't squat the rear as bad. ('pending how heavy your working with)
I had a big heavy deck on yrs ago - before the flatbed. And come to find out - my truck came stock 1 ton 4wd dually ... with NO rear stablizer setup!
IMO THAT is the first thing to answer your sway issue! But there is safety in duals.
On heavy semi packed snow roads I can float the back end. But the front end pulls it and keeps the rear only dancing. (empty/fast - in just the right conditions)
With the flatbed the sleds are lower and easier to load, don't catch as much wind, etc... I have a wood deck and unless it is covered in ICE I don't tie down the back end of the sleds at all. Keep in mind that I will run 500 miles min and of that generally 80 klicks of bush road. The carbides dig into the wood and they never move either. I toss on a ratchet strap from the trailing arms to the headache rack just fer grins, but I don't git too crazy about it. If that sled comes off - there was already a massive problem 2 seconds before that!
Run down the rd in the fast lane going around trailer after trailer. (Make sure to get into fast lane at slow speed and THEN speed up to avoid the spin factor. LOL!) I run down the windy/hilly/icey mtn roads like it's summer. And then I hafta slow down to wait to see a chumm with a trailer in my mirror sometime....
I also have a goose pin burried in there as well.
I can also use my rear view mirror with sleds or ATV's on board too!
I dare say tho - that soon after this pic was taken that I did NOT make it to the top of "Jeep Hill" the first try after this surprise snow. But I WAS running baldies as well. Winter tires generally don't go on untill Thanksgiving. (US) (Two sets of rims/tires - always in rotation)
I have ran BFG All-Terrains for 25 yrs. This truck does very well with them in the snow.
Ramps stow IN the deck too!
Just realized that this was a spring-time thread. So what did we git then?
